Chris,

I was just able to pick up the amp on Thursday and have been playing it ever since.
The experience has been wonderful and I am like a kid pulling out all my records to see what they sound like now.
Great craftsmanship and execution, I am really enjoying it so far.

Thanks Chris,
Ty Ohanneson
